  • Patent number: 10823363
    Abstract: A vehicular lamp capable of producing a flow of light emitted laterally and capable of emitting light with good appearance is provided. The vehicle light includes: a light source, a reflector that reflects the light from the light source laterally, and an inner lens that allows the light reflected by the reflector to be projected laterally. The reflector has a reflecting surface on which a plurality of reflection cuts are periodically arranged in a front-rear direction thereof. The inner lens has a lens surface protruded from a surface facing the reflector so as to face the reflecting surface. The lens surface has a shape extending in the front-rear direction while being curved convexly in a vertical direction, and a radius of curvature of the lens surface in the vertical direction gradually increases from a proximal end side to a distal end side of the lens surface.

  • Patent number: 10808906
    Abstract: A method for obtaining a luminous device the turned-on aspect of which is different from the turned-off aspect, the device including a mask that is able to be partially passed through by light, one or more light sources, and a closing outer lens that is placed downstream of the mask. The one or more light sources and the mask are arranged with respect to one another so that the mask directly or indirectly receives the light rays emitted by the one or more light sources and so that only some of these emitted light rays pass through the mask. The method includes a step of arranging the one or more light sources in the luminous device in number and in power so that the light rays exiting from the luminous device form a signalling light beam.

  • Patent number: 10797209
    Abstract: A chip scale packaging (CSP) light emitting diode (LED) device includes a flip-chip LED semiconductor die and a beam shaping structure (BSS) to form a monochromatic CSP LED device. A photoluminescent structure can be disposed on the LED semiconductor die to form a phosphor-converted white-light CSP LED device. The BSS is fabricated by dispersing light scattering particles with concentration equal to or less than 30% by weight into a polymer resin material, and is disposed adjacent to the edge portion of the photoluminescent structure or the LED semiconductor die; or disposed remotely above the photoluminescent structure or the LED semiconductor die. The BSS disposed at the edge portion of the device can reduce the edge-emitting light of the device; while the BSS disposed at the top portion of the device can reduce the top-emitting light of the device, therefore shaping the radiation pattern and the viewing angle of the device.
